# Deploying (Setting up a production environment) There are a few things you'll want to do with your application before moving into production. ## Bootstrap The `bootstrap.php` file covers most of the global settings that would change between environments. Generally you should make the following 3 changes: 1. Setting the [KO7::$environment](../api/KO7#property-environment) variable to `PRODUCTION` 2. Enable caching and disable profiling in the [KO7::init](../api/KO7#init) call 3. Change the [Cookie::$salt](../api/Cookie#property-salt) ## Configuration Change the `url.php` configuration and edit the `trusted_hosts` section. Add your production environment domain(s) into the list and remove the developing environment domain(s). Also check your other configuration files (for example if you use the Database Module check your `database.php` configuration file).
